About this map

The Lower Borrego Valley is captured here during the late 1950s, a period when the desert landscape remained sparsely settled and defined by its harsh hydrological realities. Evidence of earlier human activity is marked by the Little Borego (Site) and the Old Kane Spring Road, which traverses the Ocotillo Badlands in the north. The map underscores the critical importance of water in this arid climate, noting several inactive sites such as Baileys Well (Dry) and the County Well (Dry) Spring.

Southward, the topography rises sharply into the Fish Creek Mountains, where industrial utility is indicated by a Mining Railroad and several quarries. Large portions of the western terrain are managed as part of the Anza Borrego Desert State Park, preserving landforms like Split Mountain and Cerro. This survey reflects a transition where traditional desert transport routes were being superseded by systematic state park boundaries and industrial mining ventures.
